DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to easily replace various beds such as mats and futons, turn over the upper body, change clothes, etc. It can be changed from a bed to a hammock that can be adjusted in height, the height of the lower limbs and upper body can be adjusted, and the posture can be changed smoothly from a sleeping position to a sitting position, sitting on a chair or toilet installed on a low bed. The present invention relates to a medical treatment bed that can be moved and easily moved to a wheelchair, a bathtub, or the like.

[0002]

2. Description of the Related Art Conventionally, there is a medical treatment bed in which a bed is folded in two at the center and one of the beds is changed in angle and only the upper body is raised.

[0003] Further, there is a "medical bed" of Japanese Patent Application No. 328363 filed on Oct. 27, 1994 by the applicant of the present invention, and the claims include "freely changing the vertical and back angles. It has an upper body support that can perform an operation, and a lower limb support that can freely move up and down, and does not have a support at the waist portion, and is usually lowered to the upper body support And the lower limb support portion cover the upper surface of the mat or futon on the bed body. "

[0004]

The former medical bed has eight problems. First, there is a hard boundary in the center of the structure, and even if a mat or a futon is laid, the user feels uncomfortable and cannot sleep comfortably. Second, when bedridden, replacing the futon on the bed is a heavy labor and is often left unattended, which is not hygienic. Third, when you change your clothes, you have to lift, turn, and pass under your waist, which is hard work. Fourth, when moving the patient to a wheelchair or bathtub by hanging it with a lift or the like, it is hard work to move the patient to pass the belt under the body. Fifth, when bedridden excretion is required, the nurse has to put a portable toilet under the waist, which is a heavy labor, and the patient has to excrete in bed while lying down, which takes time and constipation. Easy to be. Sixth, if you raise your back or change your clothes or excrete on the bed, the sheets will always be disturbed,
The disorder must be corrected while the patient is asleep, which is hard work. Seventh, the height of the bed is fixed and cannot be adjusted to the optimum height for each patient or nurse. Said 1
Due to the problems (1) to (7), caregivers often hurt their arms, knees and lower back, which is a serious social problem. 8th
Is a problem common to all bets. If you become bedridden for a long period of time, your weight will concentrate in several places and compress blood vessels, causing a floor shift, making it extremely difficult to sleep.

[0005] The present applicant has invented the latter "patient bed" of Japanese Patent Application No. 328363/1992 in order to solve the above problems 1 to 6. In fact, the present invention has solved all six problems of the conventional medical bed.

[0006] However, there are three problems with the "medical bed" of the Japanese Patent Application No. 328363 in 1992. First, the bed height is fixed and cannot be adjusted to the optimal height for individual patients or nurses (typical bed heights are 5
About 0cm. ).

Secondly, in the specification of Japanese Patent Application No. 328363/1992, the first to fourth lines on page 3 of the specification, "The upper body support 1 and the lower limb support 2 are raised together. As shown in FIG. 1 (B), the body load is completely separated from the mat or the futon 4 and is supported only by the upper body support 1 and the lower limb support 2, so that the patient 5 is in a state of being suspended in the air. However, this so-called hammock state is a temporary transition state before changing clothes or sitting in a toilet or the like, and the patient is suspended in a position higher than the bed (mat or futon 4) indefinitely and put in a dangerous state. I can't go. Even if there is a need to change the patient's mood or prevent the floor from shifting, it was not possible to create a safe hammock at a height below the bed.

Third, in the specification of Japanese Patent Application No. 328363/1994, page 3, line 8 to line 10, "When sitting on the bed 6 on the toilet 6, first, as described above, After raising the supporting part 1 and the lower limb supporting part 2 together, the toilet 6 is placed on the bed. When the upper body supporting part 1 is raised and the toilet seat is seated, the lower limb supporting part 2 is lowered. " There is a typical height 40c on a typical 50cm height bed
If you install a m-sized toilet and chair, the height is nearly 1m and 90cm
The patient sitting there will feel the danger of falling to the floor, the fear of heights resulting from too high visibility, and the reduced willingness to excrete.

An object of the present invention is to provide a medical treatment bed that solves all the problems of the conventional medical treatment bed described above.

[0010]

According to the present invention, there is provided a floor base, and two movable parts arranged on the foot and head of the floor base so that the height of the floor base can be adjusted by power of a cylinder or a motor. , A bed of an independent structure, which is provided with a fixing hole on the left and right sides of the head and feet with a bedding such as a mat or a futon on the upper surface and located at the center of the floor,
It is detachably stretched to the required range such as excluding the whole of the left and right foot arms or the waist part, and the left and right foot arms that protrude toward the head to the left and right wider than the bed stand on the movable part of the foot. A flexible and air-permeable mesh-shaped or cloth-shaped lower limb support member, a head-side arm wider and wider than the bed table and protruding toward the foot on the movable part of the head, and left and right heads The left and right backrest arms, which are arranged on one arm and whose angle can be adjusted by the power of a cylinder or motor, etc., and the flexible ventilation that is detachably arranged in the required range such as excluding the entire left or right backrest arm or the waist part A mesh-shaped or cloth-shaped upper body supporting member, and a fixing device such as a knock pin arranged on the left and right sides of the foot arm and the head arm and capable of releasing the bed base through fixing holes. By left and right feet Leg support member and the upper body support member is related to care bed, characterized in that arranged so as to cover the upper surface of the bed when a fixed bed base between the over arm and head side arm.

[0011]

The operation and operation of the medical treatment bed will be described.
When normally used as a normal bed, as shown in FIG. 1 (A) and FIG. 5 (A), the footsteps respectively protruding from the two movable parts 3 arranged on the foot and head of the floor base 1. The arm 7 and the head arm 9 are adjusted to an appropriate height of about 40 to 50 cm from the floor by the power of the cylinder 2 or a motor. As shown in FIGS. 2 and 4 (A), between the left and right foot arm 7 and the head arm 9 at the same height by a fixing device 12 such as a knock pin, By inserting the pins 13 of the fixing device 12 into the left and right fixing holes 5, the bed 6
Is fixed. The bed 6 can be freely adjusted from the lowest floor 1 shown in FIG. 5B to the highest height by the power of the cylinder 2 or motor.
A bed 4 such as a mat or a futon is laid on the upper surface of the bed 6. When the bed 6 is fixed, the lower limb support member 8 and the upper body support member 11 cover the upper surface of the bed 4. Since the lower limb support member 8 and the upper body support member 11 are in the form of a mesh or cloth which is flexible and has good air permeability, the lower limb support member 8 and the upper body support member 11 have an integral relationship with the surface of the bed 4 so that there is no sense of incongruity even when lying down. It is the same as sleeping directly on a mat or futon. still,
Although not shown in the drawings, when the patient 14 actually lies down, the bed 4 sinks and the lower limb support member 8 and the upper body support member 11 bend.

When the bed 6 on which the bed 4 is laid is released from the foot arm 7 and the head arm 9, the bed 6 is first moved to the floor by the power of the cylinder 2 or a motor as shown in FIG. Then, as shown in FIG. 4B, the pin 13 of the fixing device 12 is pulled out from the fixing hole 5 and released.

As shown in FIG. 5 (C), the height of the foot arm 7 and the head arm 9 is adjusted by the power of the cylinder 2 or a motor. Then, the body load is completely separated from the bed 4 and the lower limb support member 8 and the upper body support member 11
And the patient 14 is in a state of being suspended in the air. Since the hand, the belt and the like enter from between the lower limb support member 8 and the upper body support member 11, the waist circumference of the patient 14 is completely free,
Work can be performed freely without lifting the patient 14. Since the lower limb support member 8 and the upper body support member 11 are flexible, the orientation of the body can be easily changed. Lower limb support member 8
The height of the body support member 11 can be freely adjusted to an optimal position, so that the hammock state can be safely performed for a long time. When in a hammock state, weight is widely distributed, blood circulation is improved, feeling of security is easy, feeling comfortable, it is possible to prevent bed slippage, sleep is not painful, and it is very helpful for nursing care. Although not particularly shown, the lower arm can be raised by raising the foot arm 7 or the upper body can be raised by raising the head arm 9 depending on the symptoms and mood of the patient.

When raising the upper body, the backrest arm 1
0 is adjusted by the power of the cylinder 2 or the motor. When the bed 6 is released from the foot arm 7 and the head arm 9, the upper body is raised in a hammock state. When the bed 6 is fixed to the foot arm 7 and the head arm 9, the load on the upper body is transferred from the bed 4 to the upper body support member 11 and supported.

The lower limb support member 8 removably stretched on the foot arm 7 and the upper body support member 11 removably stretched on the backrest arm 10 are made of a cloth even if they are flexible and have good air permeability. It may be made according to the condition or purpose of the patient 14, whether it is made up of the foot arm 7 or the backrest arm 10 or it is made up by removing the waist. For example, the chair or toilet 15
When sitting on the waist, the waist portion of the lower limb support member 8 is shortened or a hole is removed, and if the backrest is only the head and back, the waist portion of the upper body support member 11 is shortened or a hole is removed. If the whole body including the waist is to be put into a hammock state, the lower limb support member 8 and the state support member 9 are arranged to be stretched over the foot arm 7 and the backrest arm 10.

When the user sits down on the bed 4 in a chair or toilet 15, firstly, from the state of a normal bed as shown in FIGS. 1A and 5A, as shown in FIG. 5B. Then, the foot arm 7 and the head arm 9 are lowered by the power of the cylinder 2 or a motor, and the bed 6 is placed on the floor 1 so that the fixing device 1
2 is released, and then, as shown in FIG.
Alternatively, the foot arm 7 and the head arm 9 are raised by the power of a motor or the like, and a chair or a toilet 15 is placed under the waist of the bed 4 and installed. Then, as shown in FIG.
Or a cylinder 2 or a motor provided with the back arm 10 and the head arm 9 by lowering the foot arm 7 and the head arm 9 by the power of a motor or the like until the waist of the patient 14 is placed on the chair or the toilet 15. Patient 1 standing up with power such as
4, and then, as shown in FIG. 5 (E), only the foot arm 7 is lowered to the floor 1 by the power of the cylinder 2 or motor of the foot, and the patient 14 is lowered to the bed 4. And stabilize. The lower limb support member 8 does not hit the chair or the toilet 15 as long as the lower limb support member is removed. The chair or toilet 15 can be installed at the lowest level closest to the floor, so it is safe, there is no fear of heights, it does not interfere with willingness to excrete. May be. In FIG. 5, the chair or toilet 15 in (E) is at a lower position than the usual bed height in (A), and is stable and very safe. In addition, when the patient is seated on a belt such as a lift and moved to a wheelchair or a bathtub, the same operation can be easily performed.

By performing the above operation in reverse, the bed can be returned to a normal bed.

Even when the user is turned upside down, changed clothes, or uses a chair or toilet, the sheets are not disturbed because the lower limb support member 8 and the upper body support member 11 cover the bed 4 or float the patient 14.

The power is not particularly limited as long as safety is maintained. It may be a motor, a hydraulic or pneumatic cylinder, etc.

[0020] The physical burden of the caregiver is greatly reduced,
It can release you from hard work.
